so i paid for buckshot roulette and thats not my neighbor and after downloading them they make my entire pc unresponsive and the games are unresponsive too! I have a amd pc but don't know the specs, i wanna get my moneys worth! ps: only task manager and itch io games stop working, steam games work buttery smooth.
